How Installing Energy-Efficient Windows in Lakewood Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, including:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Lakewood, that’s about 460 pounds per year on average.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Lakewood

When considering window installation, each company provides varying services and costs. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Even though the national average cost to replace a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, like size, the location of your home, material, type, number of windows and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Lakewood home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Something else that affects the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. Because these installations are more involved, they will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which type of window installation service you need, your installer can advise you. Generally, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lakewood

In our search to make your home improvements easier and more eco-friendly in Lakewood, the EcoWatch team evaluated many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Lakewood and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Lakewood so you can find the best window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have good things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Lakewood, CO Window Replacement FAQs

What is the average cost to install windows?

The average cost of installing a window can range between $450 and $650. There are many factors that influence the cost, including the number of windows, how energy-efficient the windows are, styles and sizes of windows, your property’s location, local labor costs and the materials used in designing the windows.

What type of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
